The simplest and most effective way is jogging. It must be noted that your running speed should keep your heart rate in the aerobic stage. In other words, you can only burn fat if your heart rate is within this range. And the jogging time must be more than 40 minutes. Only the sugar in the body is consumed 40 minutes ago, and the fat is consumed 40 minutes later. Just run 1 hour every time, and you can add more time in the future.
